I've never really watched his show so have never seen anything of his beyond those occasionally insane clips people post when he goes on a massive rant, but I know plenty of people who watch his stuff ironically and find him entertaining in the way you would an insane comic book villain or something. Because the guy, undoubtedly, is as entertaining as he is insane. But the problem is that his insanity isn't just something arbitrary for his own amusement; as we've seen with Sandy Hook it has a very direct impact on those it targets. Which is something I imagine a lot of people forget.
